On Tuesday, Wakefield Council's cabinet will decide if a plan for the town's schools to form a trust with businesses outside the local authority should go before the schools' adjudicator.

This independent body resolves local disputes over the reorganisation of schools.

The trust plan has met with mounting opposition since it emerged a US firm linked to nuclear warheads was involved.

Jacobs Engineering is a strategic partner at Aldermaston Atomic Weapons Establishment, which makes warheads for the Ministry of Defence.

Its Leeds-based subsidiary, which builds roads and bridges, would be a trust member.

The Campaign Against Trust Schools (CATS) has said because Wakefield Council would also be a member of the trust, it should ask for an independent review.

And it said not enough parents had a say on the plan, with just 72 responding to questionnaires sent out by the schools.

But a report to Tuesday's cabinet meeting said the consultation had been adequate and there was no legal requirement for the plan to go before the adjudicator.

Sally Kincaid, local secretary for the National Union of Teachers, said: "We would hope this would go before the independent adjudicator because Wakefield Council is a trust member and we don't feel parents were properly consulted."

Ossett School and seven of its feeder primary schools are involved in the trust.

Leeds Metropolitan University, computer firm VdotCom, Liverpool John Moores University and Niels Larsen Sports Equipment would be trust partners.
